AP Scores and credit?

I got a 4 on AP Calculus AB and a 3 on AP Chemistry this year. I also got a 4 on AP Statistics.

I'm really hopeful that my scores are good, I mean, I do try very hard. I wanted to take AP Physics at my school because I plan on majoring in Physics or Astrophysics, but I'm going to dual enroll my senior year in high school in a little not so good college with it.

So yeah, since it's time to start applications, I was thinking about which schools to apply to. I really want to go to the University of Florida, I've heard that they have a good physics program. But I also heard that Florida State University has an awesome lab. I have a dream... That some day, I will get into MIT, but that's kind of for fun. I doubt I'll be able to get in to MIT for physics, but I won't get in if I don't apply.

Anyway, will my scores of only 4's be good enough for good schools like UF? I am a well-rounded student, not in just academics, so I think I'll get in, but I want the credit for the AP classes as well.
